I just installed a new Delphi H6 compressor but discovered that I cannot turn it by hand - I want to circulate the oil that I put into it. Some documentation that I found states that part # CB10049 (or a spanner wrench) is used to rotate the compressor. That tool is way expensive and not easily found.
Does someone have an alternative way of rotating this compressor or a pic of a tool that can be used for this model?
Here is a pic of the front of the compressor:
You could just span a long screwdriver across two of the BRT's (Big Round Things) on the clutch plate and pull on the handle end of the screwdriver. If it still won't turn with that moderate force, it is defective and should be returned to the supplier.

Just mount it and turn it on after charging- it will turn fine--no need to "distribute oil" that is a wive's tale- all factory installed compressors at assembly plant are never rotated!
The compressors have their shoe ball shoes adhering to the swash plate from sitting for an extended period (shelf life) I studied numerous tight returns- and placed them on test stands- they do come on and they do work fine.. Unless you like to continuously return items for fun- there is no need to return it..
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
I am not concerned that it is bad out of the box.
Here's another quote from the H6 manual that has me concerned about pre-rotating it. Let me know if you still disagree:
"The H6 compressor is built using very tight tolerances and the compressor clutch will not be able to be
turned by hand. Compressor turning tool part number CB10049 (or a spanner wrench) is used to rotate
the compressor before installing the compressor on the vehicle.
"4. Mount the compressor in a suitable holding fixture so that the clutch plate can be rotated. This
can be a vise with Ã¢ÂÂsoft jawsÃ¢ÂÂ or even on the engine Ã¢ÂÂ so long as the clutch face is accessible where the
turning tool and a wrench can be used to rotate the compressor. The torque needed to break in the
compressor requires it to be secured in this fashion.
5. Install a few drops of oil on the threads of the CB10049 turning tool and thread the tool into the
threads of the clutch face.
6. Using a suitable wrench rotate the compressor a minimum of four (4) turns. It can take upwards
of 80 ft. lbs. to rotate the compressor. Think along the lines of installing lug nuts when changing a tire.
It is expected that the breakaway turning torque of the H6 compressor after breaking in the compressor
can be as high as 45 Ã¢ÂÂ 50 ft. lbs.
a. The turning tool has a maximum torque rating of 90 lbs."

OMG! Is that a typo as 80 ft/lbs is a lot of torque. Most third party spanner wrenches made for that aren't that long.
